Replacing the battery: 2145-SV1

Following all safety notices, you can replace either battery for the SAN Volume Controller 2145-SV1 node.

Before you begin

Before you replace the battery, consider the following conditions:
  • A battery can be replaced with the 2145-SV1 node powered on if one of the following situations is true:
    • A fix procedure directed you to replace this battery, and identified which battery to replace by flashing the battery fault LED.
    • The service assistant GUI or the lsnodebattery command identifies it is safe to remove this battery.
    • The node status is service or candidate; the node status LED is flashing once per second.
    • The battery slot is empty.
    • The battery fault LED is on.
    Important: If at least one of these conditions are not met, then the node might change states, leaving the system state and entering the service state. This change of state happens because the batteries do not have enough charge for the system state and I/O cache to be saved to disk.
  • Both batteries can be replaced when the 2145-SV1 is powered off.
  • Locate the battery documentation and follow those instructions, in addition to these instructions.
  • Install the battery in battery slot 1 or 2 of the 2145-SV1 node.

Procedure

  1. Read the safety information before you remove and replace parts, as described in Preparing to remove and replace parts.
  2. Touch the static-protective package that contains the battery to any unpainted metal surface on the node, then remove the battery from the package and place it on a static-protective surface.
  3. Align the battery assembly with the battery slot guide rails, as shown in Figure 1.

  5. If you removed the node from the rack, replace the node in the rack, as described in Replacing a node in a rack.
  6. Verify that the following processes are complete:
    • All cables, adapters, and other components are installed and seated correctly
    • All internal cables are correctly routed
    • If you disconnected the Fibre Channel and Ethernet cables, make sure that each cable is reconnected to the same port from which it was removed.
  7. If you removed the power cords, replace the power cords. When the power cord is plugged in, the 2145-SV1 node turns on.
